here are the stats for Sabrina's Kadabra and Sabrina's ESP

Sabrina's Kadabra 70 HP
P Life Down
Flip a coin, if heads keep adding damage counters until the Defending Pokemon
only has 10 HP left.

P2 Psyshot 30

RC 2
Weakness P

Sabrina's ESP

Attach this card to one of your Pokemon. After your turn, discard this card.
If the Pokemon this card is attached to requires you to flip a coin, and you
are not satisfied with the outcome, you may do that attack again (you must do
over all costs and anything else that an attack requires you to do.)

Now with a Pluspower, Life Down is an immediate knock out! But what if you
get tails? do it again with Sabrina's ESP. Another good idea is to attach
Sabrina's ESP to Exeggutor with a hundred energies :-)

I have a question about Life-Down that all my friends are asking. What about
resistance? do you just add damage counters until they have 40 HP left? Or do
you do it normally? I hope WOTC clears this up for everybody.
